If everyone is forced to play draft, most won't play at all. If everyone was willing to play draft, they'd be doing it already. Removing blind pick won't change anything but kill dominion. It's already dead enough.

Assuming Draft Queue times were the same as Blind Pick, this still doesn't solve anything. If anything, it could make things worse since if the other team got their hands on Kass, Kha, Amumu, Jayce, Nidalee, Wukong, Urgot, Lulu, Zyra, Elise, Evelynn, Teemo, or Nunu, people would dodge. Even including the six bans, it will be a contest of who has more OP champions. If your team has less OP champions, someone will dodge. Just because you are confident, doesn't mean your teammates will be.

Proper Balancing and bug fixes should be the number one priority for Dominion. The only way I could think of ranked working out is if they added ten bans like DD. Which is very unlikely. Adding ranked now just creates a frustrating atmosphere. After proper balancing and bug fixes, ranked being implemented is practically implied. To be honest, if Riot is truly willing, they could get this down in three or four patches. They would require a lot of Dominion changes, but to be honest, it would be the equivalent to Dominion's "pre-season" changes.
